Darren, although I am not sure about adding livestock, the idea may help. I disagree about the nutrients, as they are there because they are not being removed. If clams or whatever consume them, then there not a problem anymore.

I do agree, we need to find the root of the problem though. I dont know if phosphate loaded rock could produce that much algae. What we need to do, is someone with a honkin skimmer, to see if it clears it up.

If massive water changes are done and no other parameters changed, and the problem remains, then its either the rock, sand or make-up water.
